06 tổn thất lớn ảnh hưởng đến hiệu suất tổng thể thiết bị OEE
Trong quá trình hoạt động sản xuất, chỉ số hiệu suất tổng thể thiết bị OEE (Overall Equipment Effectiveness) đóng vai trò quan trọng trong việc đo lường hiệu suất của thiết bị và nhà máy. Một chỉ số OEE cao thường tương đương với một môi trường sản xuất hiệu quả và năng suất. Tuy nhiên, để đạt được chỉ số OEE cao, các doanh nghiệp cần phải nhận biết và khắc phục những tổn thất lớn ảnh hưởng đến hiệu quả thiết bị.
Có 06 tổn thất lớn gây ảnh hưởng đến chỉ số hiệu suất tổng thể thiết bị OEE – một chỉ số quan trọng đo lường hiệu suất tổng thể của hệ thống sản xuất:
1. Tổn thất do hỏng hóc của máy móc, thiết bị:
Hỏng hóc của máy móc và thiết bị thường là loại tổn thất dễ dàng nhận biết nhất trong quá trình sản xuất. Đây là những vấn đề như hỏng hóc của khuôn/gá, thiết bị không hoạt động đúng cách, hoặc lỗi về cơ/điện của thiết bị. Những sự cố này gây ra thời gian dừng máy và gián đoạn quá trình sản xuất. Để giảm thiểu tổn thất này, quan trọng phải thiết lập một quy trình bảo dưỡng định kỳ để phát hiện và khắc phục các vấn đề kỹ thuật kịp thời.
2. Tổn thất về thiết lập và điều chỉnh thiết bị:
Quá trình thiết lập và điều chỉnh thiết bị không chính xác cũng gây ra mất mát hiệu suất. Điều này thường xảy ra khi thiết lập vào đầu ca không đúng cách, thay đổi đơn hàng, hoặc khi có sự thay đổi về thông số kỹ thuật. Để giảm thiểu tổn thất này, cần phải có các hướng dẫn cụ thể và tiêu chuẩn cho việc thiết lập và điều chỉnh thiết bị.
3. Dừng vặt khi vận hành thiết bị:
Những dừng vặt ngắn thường xuyên xảy ra do các sự cố như kẹt/tắc, lỗi dẫn hướng, hoặc các sự cố nhỏ khác. Mặc dù thời gian dừng máy ngắn, nhưng chúng có thể tích lũy và gây gián đoạn quá trình sản xuất. Để giảm thiểu tổn thất này, cần xây dựng các quy trình xử lý sự cố nhanh chóng và thực hiện bảo dưỡng định kỳ.
4. Thiết bị vận hành với tốc độ thấp:
Trong một số trường hợp, thiết bị được vận hành ở tốc độ thấp hơn so với mức tiêu chuẩn, dẫn đến mất mát hiệu suất. Nguyên nhân có thể là do môi trường không phù hợp, lỗi thiết bị, hoặc nhân viên thiếu kinh nghiệm. Để khắc phục, cần phải thiết lập các chương trình giám sát và đo kiểm thường xuyên để điều chỉnh tốc độ vận hành.
5. Sai lỗi khi khởi động, tắt máy:
Các sự cố khi khởi động, tắt máy hoặc điều chỉnh thiết bị cũng gây ra tổn thất không chỉ trong thời gian dừng máy mà còn trong việc tạo ra các sản phẩm lỗi. Để giảm thiểu tổn thất này, cần phải phát hiện và xử lý các sản phẩm lỗi kịp thời để tránh ảnh hưởng đến chất lượng và quy trình sản xuất.
6. Sai lỗi trong sản xuất:
Khi thiết bị hoạt động bình thường nhưng tạo ra sản phẩm lỗi, điều này dẫn đến việc sản xuất sản phẩm không đạt chất lượng. Để giảm thiểu tổn thất này, cần thiết lập các quy trình kiểm tra chất lượng sản phẩm và thực hiện kiểm tra trước khi đưa vào vận hành hàng loạt.
Ngoài 06 tổn thất lớn này ra thì còn có tổn thất do Dừng máy theo kế hoạch: Loại thất thoát này do có kế hoạch và không gây ảnh hưởng đến hiệu suất tổng thể thiết bị OEE tuy nhiên sẽ gây ra kéo dài thời gian sản xuất dẫn dến giảm sản lượng sản xuất của thiết bị.
Kết luận: Tổn thất lớn đối với hiệu suất tổng thể thiết bị OEE không chỉ ảnh hưởng đến hiệu suất sản xuất mà còn gây ra lãng phí về tài nguyên và chi phí. Mục tiêu của các chương trình Bảo trì năng suất tổng thể TPM (Total productive maintenance) và giám sát OEE (OEE Tracking) là loại bỏ và giảm thiểu các tổn thất này để tối ưu hóa hiệu suất sản xuất và tạo ra một môi trường sản xuất hiệu quả và bền vững.
He quickly supported Qiao Shan and angrily Junior brother Liang, what exactly do you want to do Liang Zhongtian turned to look at Qingyang and said, I owe him a promise, I owe him a life, and I have to pay him back now.After being cleaned up in this way, nothing would be left behind.
It can be said that the damage was heavy. In fact, originally the losses on the monks side were not that great, but in the end the poisonous sac of the Symphony Spider exploded, and many of them had no time to escape and were affected.No wonder he dared to practice alone in Chaotic Demon Valley.
Kou Yuchang had nothing to say for a moment and could only roll his eyes, and then angrily sat on a table next to him.Seeing the scarred face in the room, Deng Changting did not hesitate at all.
These years are relatively small, and they should have grown by themselves later.The first one was of course Tong Yan. It didn t take long for Tong Yan to break through the late stage of Qi refining, but he was assigned to the inner courtyard as soon as he entered the Qingfeng Palace.
Decades have passed since the one eyed dragon Lengyu incident.If you take one bite, you will die on the spot What can be so poisonous Qingyang went through all the information about monsters and spiritual insects that he knew about spiders, but he still couldn t find one that could evade spiritual thoughts.
How dare you say that He Lanfeng was not sent by your Liang family He Lanfeng Hearing Qingyang mention this name, Liang Zhongtian couldn t help but feel his heart sink.Instead of lingering in this Yinfeng Gorge, it is better to fight vigorously and kill a hundred people.
He didn t expect Qingyang to grow so fast. He could block his fatal blow just after breaking through the foundation.Qingyang has been practicing in seclusion these years, barely leaving home, and rarely interfering with the outside world.
They were far away from the main battlefield of Qiyun Master and Madam Xiancai, but just in case, they all chewed up the Three Star Clear Miasma Pill in their mouths.However, Liang Zhongtian never showed a trace of disgust or impatience because of these things.
At the top of the steps, at the entrance to the second and third floors of the Geocentric Tower, there is also a hidden formation.By that time, we have already finished. If I can continue our plan in a hidden place, what can the seven immortal sects do to me Tao Zhengyou said proudly.
In that case, the entire rat group could not be described as being injured, but suffered heavy losses and suffered heavy losses.After missing Qingyang, his speed did not slow down and he directly grabbed the bagel in front.
The disciples of the Yuling Sect decided to cut through the mess quickly.A flying spiritual weapon has a single function, is fast, and consumes less real energy, while controlling a flying sword is slow and consumes a lot of real energy over a long period of time.
He was really worried that the people in Jingfeng Pavilion would go crazy and ambush someone in the sect to kill him.This battle is even more unbeatable for the Jingshan Rat.
A greater danger, because that swarm of blood bats alone couldn t do it.Therefore, everyone rushed during the day and rested at night.
Qingyang s ability to reach this point must be due to luck, but it also has a lot to do with his strength.The instigator is very incompetent, so we should Destroy them all in one go.
Seeing the other party s frightened look, Qingyang knew that this should be the bottom line of the price, and the refining The shops opened by Qiyuan are semi official, and almost all prices are clearly stated.I accidentally pierced a hole in his sleeve. Later, the family leader urged him to come to Phoenix Mountain with him, but he didn t have time to change it.
After the attack by the Mountain Shocking Rats, everyone judged that there should be a vein of spirit stone near the Mountain Shocking Rat s lair, so Senior Brother Li suggested that everyone search separately and meet again after half a month.However, the three masters united and naturally would not let him go so easily.
The more than thirty advanced Mountain Rats that were still attacking received the order and immediately stopped attacking and retreated.Yang was frightened by this move, so he only paused slightly before continuing to charge.
Several leaders walked around the valley and quickly selected a place to set up the formation.When would he be able to practice to this level and be a leader in Jiuzhou Continent As a disciple of the Demon Suppressing Hall, Lu Feng saw that the ancestor of the sect suffered a loss, but he could not do anything to help him.
The entire Dantian seemed to It felt like it was about to burst, the swelling was uncomfortable, the true energy was still coming in, but there was nothing that could be done about it in the Dantian.Qingyang was unwilling to give in and tested Songhe Lao Dao several times.
How could such a powerful team be missing one of them Qingyang said, I m used to being alone and don t like to form groups with others.It seems that this is the lair of the living dead. Based on the distance traveled by the living dead before, Qingyang could tell that this place was obviously on the ground, but the surroundings were closed.
He had considered it when he was in Chaos Demon Valley.The biggest change is the increase in space. The area has once again expanded nearly ten times, with the length and width exceeding 400 feet, and the total area is more than 2,000 acres.
There was just a loud roar, and the Hantan Sword was knocked back more than ten feet away.The Mountain Shocking Rats blocking him here meant that their lair was not far away.
After listening to Jiao Hong s explanation, Master Lingxu also became a little interested in Qingyang and said, The secret palace has not yet been opened.The large group of Mountain Shocking Rats in front of us numbered in the thousands.
As a result, I was assigned this job by the head brother.
Due to the presence of arms, ordinary legions can only perform tasks such as defense, escort, patrol, and death
In a real large scale war, arms are more useful than any ordinary army.Roar Just as the Crystal Dragon, the Crystal Thorn, launched its unparalleled killing spree, the golden dragons also launched a formal attack
After all, the fleet is taking care of itself at this time, so why bother to keep an eye on them.
Yeah In fact, Zhao Hao noticed the strange smell coming from the front without the other party reminding him.Black warriors, corpse witches, black knights, terrifying knights
bone dragons and other high level undead are densely packed.
The number of demons continues to increase, but with the increase in the number of patrols, and Lord Memphela clearing them out from time to time, we can barely stop them Tata reported.He said hello and added friends to Li Keke, which was actually to explain why he was optimistic about the Star Language Business Group.
Beasts There are only wrong names, not wrong nicknames.But from now on, these inconveniences will end. With the input of cheap supplies from the Storm Territory, the Pale Territory doesn t have to worry about not having enough of these supplies.
Now that his flying ability is temporarily lost, there is no hope of victory at all.Aren t the demons afraid of being stabbed. Why don t you believe it We hope that the devil can destroy the resistance of all major forces, and we wish that the other party would be stronger Mia asked, and also expressed her opinion.
It s so fast because Freya is flying. Of course, Curry was caught in his claws and carried away.Although it is still dangerous, it is not impossible to succeed.
Under the undead butcher s knife, the interior of Shenmu Castle began to collapse.If this is the case, it is not surprising that the other party is silent and does not support.
Even ordinary people can easily run out of this range as long as they don t stay in place.Moreover, the robe on the other party is also more exquisite and gorgeous, and the difference can be seen at a glance.
But this explosive bomb is equivalent to the power of a fireball.After all, they don t take the lives of untouchables in their eyes.
After the Blood Sea Overlord took a deep breath, he whispered hello to his girlfriend and his deputy, and then climbed up the rope ladder alone.No wonder he would look at her differently. Soon, they arrived at the second floor of the Chamber of Commerce
Hejia Xiaobingbing reminds you after reading this, remember to collect the second floor of the Chamber of Commerce Compared with the first floor, the layout on the second floor is much more exquisite.
Let s go Zhao Hao saw an alchemy apprentice walking quickly, knowing that he was sent by Turing to guide the way, and called Freya and Feida to follow.When she said agreement , she noticed that several people had surprised expressions on their faces, knowing that she had guessed correctly.
After listening to the report, Zhao Hao was very satisfied.can all be produced on their own. Although the quality is not great, the orcs are not picky.
Unfortunately, they had no idea who the target of this interception was.At that time, the ballista can naturally play its role.
Their job was to build roads across mountains and rivers, build bridges, chop wood for fires, dig ditches and carry water, and build camps.They are replaced by flesh and blood creatures. They will die or not in this blow.
Yes, the Storm Territory does not need help, the one who really needs help is the Tianhai Alliance.If he is at his peak, his strength is at least the beginning of an epic, otherwise he would not be qualified to win that title.
It s really an exaggeration. It s a pity that Zhao Hao doesn t know Mingyi s thoughts, otherwise he would definitely tell him that he is overthinking.The weak ones even knelt down directly. Horrible Just relying on the momentum alone Being able to achieve this level shows how exaggerated the strength is, definitely beyond the championship level.
A magic battleship is enough to make people feel envious, let alone such a special magic battleship.This time when he returns, he has a good chance of being promoted to baron.
It was at this time that an explosive news came. The defense line of Eagle Claw City collapsed.Zhao Hao was also helpless about this. This is due to character But his current status is not suitable for preaching, so he can only give more life saving spells to the other party in the future.
Attack fast Maybe it took the Shadow Swordsman several strikes before the Phantom Archer couldn t shoot a single arrow.As for Memphela and Ellie, who can fight, they are leading the Storm Legion to escort the caravan to the Pale Territory.
But as long as he succeeds, his development speed will skyrocket like a snowball.As long as the ship spirit is available, there is no need to worry about trouble.
After all, the explosion alone would have completely destroyed the target, so it would be of little use no matter how high the fire damage was.Offensive and defensive reversal Just now, the other party surrounded Mia, and now he is surrounded.
Yes, there is definitely something wrong with this.
12, and theoretically 100 38. 79 equals 138. 12 this speed. Of course, this cultivation speed is almost the same as that of a Tianlinggen, but he is not satisfied yet.The green kite wooden sword scratched his arm, and blood immediately poured out.
Yunze quickly calculated in his mind that this would be a bit troublesome for the initial promotion, but it was not a big trouble.When Li Shiming was on Tianhai Island, he was reminded by many monks, including the Golden Pill monk, that his physique was too strong and he had exceeded his spiritual power by too much, which had the opposite effect and reduced his chance of breakthrough.
When the black shadow was about to reach the city wall, he saw from the blindfold that the dark blue figure overlapped with a red figure, and then the dark blue figure disappeared, leaving only the red figure moving in the other direction.There are at most first order sea monsters here, and even Ren Fei er can handle them.
It has the same powerful aura and the same sense of oppression.The flight speed is greatly increased, which shortens the time to return to the sect.
Elder Baili thought that there were still golden elixirs nearby, ready to attack at any time, so he used the blood escape method to escape, leaving Wei Yun to bear the remaining power of the explosion.Perhaps in her understanding, the formation of a landscape world formed by the sea of starlight is her greatest understanding of the world.
He exchanged an LED lamp for the high grade Horcrux Crow Wing, and received so many things that he felt like he was deceiving the children.Wang to come forward. It was just too cruel. Thirty five lives were lost like this. This is Nanling Mansion, no wonder the drums are beating, probably not only the government soldiers, but also the troops near Nanling Mansion will come at this time.
Without any hesitation, he threw the low grade hammer weapon in his hand towards the flames inspired by the intermediate attack talisman.This result is considered very good. But this was based on the IBMz15 alchemy database.
He tapped his fingers on the alchemy furnace seven times, which was the Seven Finger Alchemy Collecting Technique.He had never been exposed to the deputy positions that the other three were learning, and the skills acquired within the sect could not be taught to each other, so naturally the only ones he could help were the spiritual cultivators.
Baili Jinyan came to an uninhabited island. With a wave of his hand, a sword light flew out and opened a simple cave on the island.A monk without strength, To approach the thirty third heaven is to seek death.
But he didn t recognize most of the flavors, which was normal.The Junior Light Body Talisman he made was 20 faster than the captured Junior Light Body Talisman , and it was considered the most special of the talismans he made.
In addition, practicing the Five Elements Breathing Qi Art will have a great impact on the body.Even a slight mistake will make the spell casting impossible to complete.
The primary magic circle materials are used for training, which he can barely support at the moment.It requires mastering a lot of relevant knowledge. It also requires the inheritance monks to have magic circle talents, that is, they have a strong talent for calculations.
It is somewhat inaccurate to say that the Gatling in his hand is a middle grade magic weapon, because every part of Gatling s body can be said to be a middle grade magic weapon.He didn t know Baoze Mountain or Yi Zhen, but the one who could make the old monk in the middle stage of foundation building recognize him as his master must be a monk whose strength far exceeded that of the middle stage of foundation building.
Don t learn the Xuanming Sect s techniques. It will affect your temperament and make you bloodthirsty Master Cui waved his hand and said
Since the outermost defensive formation of the flying boat was destroyed, and Uncle Zhao had no means to repair it on his own, in addition to strong winds, there were also turbulences on the deck from time to time.
He likes to turn around and retaliate directly after being wronged.For all monks in the Qi Refining Stage and most of the Foundation Establishment Stage, Tianhai Sect and Xuanming Sect are mortal enemies.
I also have some experience in the Light Body Technique.The coexistence of Buddha and devil maximizes each other s power.
Ling Nian swept across the three golden jade slips.I feel sick even when I say it. He doesn t look like a cultivator Although Liang Yexuan was extremely fond of Senior Brother Zhang.
If Xuanming Sect really takes action against Tianhai Sect, then the war between the two sects will escalate.Thank you, fellow Taoist Li Yuanba took the monkey wine and said with a smile.
Anyone could have the means of a spiritual cultivator, and the value of the spiritual energy crops grown by a spiritual cultivator would not be enough to support this industry.When Manager Zhang heard the name, hesitation appeared on his face.
The Xuanming Sect monk dodged and turned into a black light to get closer to him.Especially the high grade spiritual veins were completely sealed by him.
The Bansheng Cave and Tianren Cave were his private caves.Therefore, the cultivation level of the great monk Luo Pei has always been at the weakest state.
Master Li, the quality of the same spiritual tea brewed by your hands has improved a lot.Otherwise, even he would not be able to bear such a huge consumption.
Li Yuanba knew he couldn t stay any longer, so he turned around and passed through the space barrier again.The earth wall only consumed a small part of the energy of the thunder and lightning, and the thunder and lightning continued to attack the magic weapon on the mountain.
Array mage is not a combat profession. It takes some time for the formation master to arrange the formation.Not to mention that Li Yuanba left safely. How could Li Yuanba be willing to leave without significant gains Regarding the loss of Qian Renzong, many rumors emerged, and these rumors raised the terror of Jianyi Chongxiao Pavilion to an extremely high level.
Starting from the top of the mountain, the unprotected rocks shattered under the impact.Li Wenfeng wanted to express his feelings, but he thought of the masters and fifty cavalry accompanying the carriage.
He put away the fragments of the Qingyuan Wooden Sword and placed them in the computer room as a souvenir.After slashing out more than a hundred swords in a row, the life breath of the bull headed creature in the late fourth level hell was completely dissipated.
They can contact the ancestors who became immortals through special means.Fortunately, he could control the Invisible Magnetism.
As long as you have enough contribution points, you can exchange them for a lot of good things.Li Shiming looked at the fourth grade elixir refining task of the sect mission.
Tan Xian Yuanying naturally recognized what kind of talisman it was, and his eyes were full of horror.The shadow of the Taiqing Black Turtle appeared behind Li Shiming.
Fellow Daoist Wang, I forgot to tell you that the mission is over and all the space acceptance talismans have become invalid.If Da Neng really wanted to target him, he would not be able to resist it.
One thousand and twenty four trial sword lights Li Yuanba muttered to himself while adjusting his breath.You must know that no matter how he blessed him in the past, the power of thunder and lightning was restricted.
Senior Brother Wu, I will be careful Li Yuanba nodded.He blocked an attack for the great monk Wang He, and another flame emitted by the red gold phoenix.
Luo Pan did not respond and refused Li Yuanba s spiritual contact.Senior Brother Tan, we missed last time. You must take us with you next time A mid stage Nascent Soul monk said.
Sex is more suitable for Wan Jianfeng. You prepare the elixir.The new mission is to go to Xiyan Continent and kill the monks of Baidi Sect.
He shook his head vigorously, as if he didn t feel good.It s great that you can come back. Capturing the Great Venerable Guangling will prevent Lianhua Temple from being too rampant Brother Ding took over the Great Venerable Guangling.
Li Yuanba ignored the craziness of the constitutional talks.
